PURPOSE:To obtain the titled photosensitive body superior in electrostatic characteristics, sensitivity, and durability, and stable in repeated uses by forming on a substrate a photosensitive layer obtained by dispersing a specified photoconductor powder into a specified thermosetting acrylic resin binder. CONSTITUTION:An electrophotographic sensitive body is manufactured by forming on a substrate a photosensitive layer obtained by dispersing a phthalocyanine type photoconductor powder into a binder. This binder is a thermosetting acrylic resin having amide bonds obtained by radically polymerizing a monomer mixture of (A) 10-50wt% styrene monomer, (B) 10-40wt% monomer of formula I (R1 is H or methyl; R2 is 1-12C alkyl), and (C) 3-30wt% monomer of formula II (R1 is same as said R1, and R3 is H, methylol, or alkoxymethyl), a mixture of said mixture and 1-10wt% alpha-methylstyrene, acrylonitrile, (meth)acrylic acid, or the like. The electrophotographic sensitive body thus obtained is superior in electrostatic characteristics and sensitivity, and stable against repeated uses, and superior in durability. |
